## Core Concept
Wilson's disease is a genetic disorder characterized by excessive accumulation of copper in the body, particularly in the liver, brain, and other vital organs. Trientine is a chelating agent used in the treatment of Wilson's disease to remove excess copper. It works by binding to copper, facilitating its excretion from the body.

## Why the Correct Answer is Right
Trientine is indeed used in the management of Wilson's disease, especially for patients who cannot tolerate penicillamine, another chelating agent. It effectively reduces copper levels by enhancing its urinary excretion. This makes option D a potentially correct statement about trientine's use.

## Why Each Wrong Option is Incorrect
- **Option A:** Without the specific details of option A, we cannot directly assess its accuracy. However, if it aligns with known properties or uses of trientine in Wilson's disease, it would be considered correct.
- **Option B:** Similarly, without specifics, we can't evaluate B directly. If B contradicts established facts about trientine, it would be incorrect.
- **Option C:** This option is stated as the correct answer but without context, we must infer. If C suggests that trientine is not used in Wilson's disease, or it does not act as a chelating agent, or another incorrect statement regarding its mechanism or use, then it would be incorrect based on the established use of trientine.

## Clinical Pearl / High-Yield Fact
A key point to remember is that trientine is an alternative to penicillamine for patients with Wilson's disease who experience adverse effects from penicillamine. Monitoring of copper levels and liver function is crucial during treatment with trientine.

## Correct Answer: C.
